Tofu-tastic! A Step-by-Step Guide to Making Tofu at Home

Watching soybeans become a fresh block of tofu is a small kitchen transformation worth experiencing. You discover its gentle soybean flavour and begin to understand the care behind an everyday food.

You do not need to be a chef. Clean equipment, patience and a few useful checkpoints will help you get started.

This guide makes pressed tofu, straining the soybean mixture before cooking. Silken tofu follows a different process: the milk sets directly in a container without being broken into curds and pressed.

What You’ll Need

For this small gypsum-based batch, gather:

• 180 g dried yellow soybeans

• 2 litres drinking-quality water for blending and rinsing

• 1½ teaspoons fine food-grade gypsum powder, using a 5 ml measuring teaspoon

• 250 ml hot drinking-quality water for mixing the gypsum

• Extra water for soaking and cooling

These quantities are a starting point for a small gypsum-based batch. The amount of coagulant needed can vary with the powder and the concentration of the soy milk. If your supplier provides different tofu-making instructions, follow its complete method.

You’ll need a blender, a heavy-based pot holding at least 4–5 litres, a fine nut-milk bag or muslin cloth, a colander, a bowl, a thermometer and a slotted spoon. For shaping, use a perforated tofu mould with a lid and a stable weight. A small colander also works, producing a rounded block.

Wash your hands and thoroughly clean the equipment and cloths before starting.

Understand the Coagulant

Heating and coagulation help soy proteins form a network that holds water. Pressing removes some water, shaping the block’s firmness.

Gypsum, or calcium sulphate, is generally mild in flavour and relatively gradual in its action. Nigari, usually rich in magnesium chloride, acts more quickly. Both can make delicious tofu, but this guide uses gypsum. Do not substitute nigari spoon for spoon. Lemon juice and vinegar may introduce sourness and a grainier texture.

Step 1: Soak the Soybeans

Rinse the beans, remove damaged ones and cover generously with water.

Soak in the refrigerator for approximately 12–20 hours, allowing longer if needed. Check a split bean: its centre should look evenly hydrated, without a hard, dry core.

Drain, rinse and discard the soaking water.

Step 2: Blend and Strain

Blend the soaked beans in batches with 1.5 litres of your measured water until very fine. Use the remaining 500 ml to rinse the blender, adding those rinsings to the mixture.

Line a colander with the straining cloth and place it over a clean bowl or pot. Pour in the mixture, gather the cloth and squeeze out the liquid while it is still cool.

The liquid is raw soy milk; the pulp is raw okara. Do not taste either; both need thorough cooking before eating. Refrigerate the okara promptly and cook it thoroughly in a suitable recipe, or freeze it for later cooking.

Step 3: Cook the Soy Milk

Heat the milk over medium heat, leaving generous space for rising foam. Stir regularly, scraping the base and corners to prevent sticking.

Bring the liquid itself to a boil. Rising foam alone does not confirm boiling.

Reduce the heat and maintain a gentle simmer for 10–15 minutes, continuing to stir. Stay nearby because soy milk can overflow suddenly.

If it scorches, avoid scraping burnt material into the milk. Straining cannot reliably remove a burnt flavour.

Step 4: Form the Curds

Turn off the heat and let the milk cool to around 80–85°C for this gypsum method. Use a thermometer rather than a fixed waiting time. If your product’s method specifies another temperature, follow it.

If a thin skin forms, gently lift it off with clean chopsticks or a spoon for a smoother result. This is the beginning of yuba, or tofu skin.

Mix the gypsum with the 250 ml hot water. It forms a suspension rather than dissolving completely, so stir again immediately before pouring.

Slowly add it across the milk while making a few gentle, broad stirring movements. Once distributed, stop stirring. Cover and leave undisturbed for 10–15 minutes.

Look for soft white curds surrounded by translucent, pale-yellow liquid. If still milky, wait another five minutes before troubleshooting; avoid repeated stirring.

Step 5: Shape and Press

Line the mould with a clean, damp cloth, smoothing out any bunching. Place it over a draining tray. Gently scoop in the curds, fold the cloth flat over them and add the lid.

For a small mould approximately 10 × 15 cm, try 500 g for 15–20 minutes for tender tofu, or 750 g–1 kg for 20–30 minutes for a firmer block. Keep the weight balanced. These are starting points: mould size, curd quality and cooling also affect firmness.

Step 6: Cool and Store

Gently unwrap and place in a clean container of cold drinking-quality water. Cool promptly, using an ice-water bath around the container if needed, then refrigerate.

Store submerged in fresh water in a sealed container at 4°C or colder. Change the water daily and use within two days as a cautious home-storage approach.

Following WHO food-safety guidance, do not leave finished tofu at room temperature for more than two hours. Water changes do not replace refrigeration.

Common Mistakes

Few curds: Check temperature, milk dilution and coagulant measurement. Follow your supplier’s instructions for adjustments rather than adding powder blindly.

Crumbly tofu: Excess coagulant or vigorous stirring may contribute.

Too firm: Reduce pressing time or weight next time.

Keep brief notes and change one variable per batch.

Final Takeaway

Making tofu once can deepen your appreciation for its flavour, texture and possibilities. Enjoy your first block simply with ginger, spring onion and a little soy sauce, or add it to a vegetable-rich meal.

Whether homemade or bought, tofu offers another welcoming way to bring more plants to the plate. Small discoveries can become everyday habits—and a path to a kinder world.
